CommonNames problem

OS is Windows 2000

I've been using SpyBot for a while, but it can't delete some stuff in a file called CommonNames. I know nothing about the file, but I'm guessing it's the source of the problem. Is this a known problem? Should I just delete the file myself?

This showed up after a recent SpyBot update. I've cleared all the temps and cookies while on selective start up. Inside CommonNames is a second file called AddressBar. In that are 8 DAT files, cnbabe.dll, and two applications, comwiz and winnet.
